Veterinary issue: Tapeworm problems are often found in the field, especially in laying chicken farms, with chicken coop (house) type, open-side battery-caged system.

It’s a chronic disease, not all chickens in a flock have the same problem. So, not necessarily all chickens have to get antihelminthic. It will cost a lot.

Worms do not spread like the viral disease, but in chickens with battery cages system, the disease is highly dependent on the carrier. This disease occurs sporadically. So mass treatment is not an urgent action.

This is actually an environmental problem, but many breeders are even more focused on the treatments done on chickens, should they focus more on environmental treatment, contamination, and carrier, insects.

Tape worm in laying hens: Veterinary

Many breeders use antihelminthics to do treatment, in this case, even they make a worm prevention program at the farm by giving antihelminthic on a regular basis in the chicken flock.

Chickens with severe worm infestations can sometimes still produce well (good performance). Indeed this will be a problem, if not given treatment. But that does not mean a flock should be done mass treatment.
